1. Measure whether there is real electricity, and replace the voltmeter with the generator.
2. Hit it automatically or manually.
3. Check and correct according to the line map.
4. The new generator or the machine that is not used for a long time is easy to appear. It can be magnetized according to the recharge button on the control panel, or the excitation winding can be magnetized with a 12V battery, the positive pole is connected to F1, and the negative pole is connected to F2. If the voltage cannot be established, Switch the battery positive and negative poles and try again.
5.cleaning is the surface of the ring, sanding the end face of the carbon brush to make the area of the arc with the surface of the collector ring more than 70%, strengthen the spring pressure.
6. clean carbon brush and carbon brush grip so that the carbon brush can move freely.
7. Check the forward and reverse resistance of the diode with a multimeter, such as damage replacement.
8. Check with a multimeter and replace if the forward and reverse resistance does not meet the diode characteristics.
9. The diesel generator set uses the multimeter 1K file to check the winding. If the resistance value is infinite, it should be turned on. Then use 1 Euro file to check. If the resistance value is zero, replace or process the winding. If it is unstable, check if the connector wiring is loose.
